Understanding Circadian Rhythm and Its Impact on Health

The circadian rhythm consists of physical, mental, and behavioral changes occurring in a 24-hour cycle, regulated by the suprachiasmatic nucleus in the hypothalamus. This master clock responds to light and darkness, signaling every cell in the body on what actions to take. Disrupting this rhythm by being awake during natural sleep times or vice versa can lead to significant health consequences, including cancer, cardiovascular diseases, metabolic dysfunction, fertility issues, and mental health disorders.
